BUILDING CONSTRUCTION.

Application filed May 23, 1918, Serial No. 236,080.

To all whom it may concern:

Be it known that I, FRANK R. HAHN, a citizen of the United r itates, a resident of Decatur, in the county of Macon and State of Illinois, have invented new and'usetul Improvements in Building Constructions, 01. which the following is a specification.

My invention relates to improvements in building construction, and particularly to that type of construction wherein the wall is composed of a plurality of pro-cast slabs or units which are supported by supporting posts or columns.

The principal object of this invention is the provision of such a construction, whereby a wall may be quickly erected and securely supported and held together.

Another purpose of this invention is the adaptation of. this idea to both single and double Wall construction.

To the accomplishment of theforegoing and such other objects as may hereinafter appear, my invention consists in the combination, construction and arrangement oi: parts hereinafter described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof, and which show merely for th purpose of illustrative disclosure, a preferred embodiment of my invention, it being understood that various changes may be made in practice withm the scope of the claims without digressing from my inventive idea.

In the drawings,

Figure l is a top plan view of a portion of a wall constructed to embody my invention, the supporting post being shown in section to facilitate the disclosure of the fastening and holding means;

Figure 2 is a top plan view of a portion of a double wall construction embodying my invention;

Figure 3 is a top plan View oi a portion of a double wall construction embodying my invention, the corner construction being illustrated;

Figure 4 is a sectional view illustrating the particular holding means for the sections.

In carrying out my invention, I provide a plurality of slabs or units 1 which are precast and preferably formed with tongues 2 and grooves 3 on its edges so that the different slabs may interfit. These slabs may be formed of any suitable material and faced Renewed May 13, 1924.

in any desired manner for ornamental and decorative purposes, as is well understood.

They are also provided with the longitudinal. metal reinforcing rod 4 which is exosed tor a portion 5, or its: length, by the cutting out of the recess 6 in one side of the top edge portion of certain slabs or units, as clearly shown in Figures 1 and 4.

In the singlewall construction, the slabs are supported by a suitable post 7, which may be precast or cast in situ and is substantially rectangular in horizontal cross section, having the vertical reinforcements 8 near each corner and the horizontal reinforcement 9 extending around the vertical reinforcements and following the sectional conformation of the post. The post is provided with the vertical groove or recess 10 which extends the full length thereof, and at certain intervals corresponding to the recess 6, in the slabs or units, is additionally recessed or cut out as at 11. These additional recesses 11 in the supporting post 7 expose a length 12 of the horizontal reintor-cement 9.

ln the erection of the single wall, as shown in Figure 1, the exposed portions 12 of the horizontal reinforcement 9 and the exposed portion 5 of the reinforcement 4: in the slabs or units, are located substantially in alignment, the cut-out portions or recesses 6 and 11, also being in alignment. As the wall is built, the holding members 13, which are shown in the form of a double hoolr, are secured over the exposed portions or the reinforcing members, and thereby hold the slabs or units to the supporting posts, and thus support the wall. l Vhen the erection of the wall is completed or has progressed a sutlicient distance, the cement is poured into the vertical groove 10 in the supporting post, completely filling the same, and also the recesses 6 in the slabs or units, and the recess 11 in the supporting posts and completely covering the hook members 13 and the exposed portions oi the reinforcements, thereby securely binding the wall together in a unitary structure, and protecting all the metal parts r'ro n exposure to the weather and the air, and preventing rust and deterioration. of the same from other causes.

It is to be noted that after the cement is poured into the groove 10 and the communicating recesses, and has set, shoulders will be provided on which the slabs or units next above will rest, so that the entire weight of the superimposed slabs will not be upon the lower ones as they are partially supported on these lugs or shoulders.

The same idea is applicable to the double Wall construction, as shown in Figures and 3, where, instead of using the supporting posts, smaller slabs or units is": of substantially the same construction as the slabs or units 1 are placed between the double arrangement' in pairs, each one hav ng the plurality of cut out portions 15 to exnosc the portions 16 oi the rein rcing me? her. Hoolr members 17 are utilized to connect these exposed portions 16 of the reii'iforci members in the slabs or units 14% and a the exposed portions 53 ot the rcinitorci a members in the slabs or units 1 of the wall. In addition tothis, the vertical reinforcements 18 may be used in the angles Formed at the intersection of these hoolr members, and when the wall is completely erected or has progressed suitliciently, cement is poured therein, and, after setting, operates to sccurely bind and hold the parts together as previously described, in connection with the single Wall construction.

The construction shown in Figure 3 is substantially the same that shown in Figure 2, with the exception that the llOOlii members 19 extend from the exposed portions oi d e reinforcements in the slabs or units 1 to the exposed portions ofthe ren orcoments in the slabs or units 14. Cement is also poured in the space formed by these slabs or units so that a proper supporting column is provided between the walls.

It is therefore seen that l have provided a very simple and eiiective construction, whereby a wall either single or double, may be quickly erected from pre-cast units and securely held and tied together as an integral structure. The Wall is strongand attractive in appearance.

What I claim is 1. A construction of the character described, including in combination, a plurality of slabs having cut-out portions, an engagement member positioned in said outout portions, supporting posts having a vertical groove and also cut-out port-ions positioned in substantial alignment with the cut-out portions of the slabs and also having an engagement member exposed therein, engaging members engaging corresponding engagement members, and a suitable plastic material disposed in the opening formed by the vertical grooves and said cut-out portions after a wall has been erected.

2. A construction of the character described, including in combination, a plurality of slabs each having longitudinal reinforcements near one edge and also provided with a cut-out portion forming a recess exposing a portion of the length of said reinforcement, a supporting post having a vertical groove, and also a horizontal reinforcement embedded therein, said supporting post also having a plurality of cut-out portions to provide recesses corresponding to the recesses in said slabs, said cut-out portions of the post exposing lengths of. said reinforcements and an engaging member engaging the corresponding expose-d lengths of said. reinforcements, and a suitable plastic. material disposed in the opening formed by said groove and said recesses.

3.
